Signed PDFs and Editing: The Truth

Digital signatures protect integrity. Any change to the content usually invalidates the signature, which is the point of signing in the first place.

What You Can Do Safely

  • Add comments or annotations (non-destructive)
  • Attach supporting files (in some viewers)
  • Create a new version from the original source
  1. Locate the original unsigned document.
  2. Make the necessary edits.
  3. Export to PDF.
  4. Send for signature again.

This preserves legal clarity and avoids disputes.

DocuSign-Specific Notes

For DocuSign:

  • Use the original source or the DocuSign document before completion.
  • Make edits.
  • Send a new envelope for signing.

Summary

If a PDF is signed, treat the content as locked. For real edits, go back to the source, update it, and re-sign. This is the cleanest, most defensible process.
